My apap pressures were a floor of 10 and a Max of 18. With this my nightly AHIs were running about 14-18. Now with a pressure of 14, my AHIs are a little better then on the apap but no where near where it needs to be.
Thanks all.
And that floor of 10cm may well have been the problem with the APAP. If you need 14cm much of the time, then a floor of 10 is likely too low for a comfortable and effective APAP range.

What were your 90% or 95% readings when using the APAP range?

How was the 14cm for straight CPAP determined? A titration study perhaps?

If your titrated pressure is at 14, if you can tolerate 14cm, and if you're still not getting the AHIs you need, then it may be that you need an APAP range of something like 14-18 or 13-18 instead of 10-18.

Open the image to full size so it is easily read.
I use Vista snipping tool to create a screen shot and crop the image at the same time.
Prt/scr key will also take a screen shot if using XP. If laptop is used sometimes the Fn key has to be pushed at the same time as the prt/scr key
I think windows 7 Home Premium has the snipping tool, Basic may not.

Once the screen shot is created save it in jpg format.
Upload the image to a host site. I use Photobucket it is free, there are others.
Once the image is uploaded then copy the ENTIRE IMG address. Be sure to include the opening and closing IMG in brackets. Paste that copied address into a post here.
Use the preview button. If you can't see the image try again because if you can't see it we can't.

I agree that a range of 14 - 18 might work well. Robysue, as you said if he typically needs 14 then 10 was too low for the minimum.

Also, since the doc originally set the max at 18 that is an indication the doc could see from the studies that he sometimes needed 18. But now the doc set him at straight CPAP 14 and the times when FeelingBetter needs 18 are problematic.

If it were me I would get an APAP on loan and set it to 14 - 18 and monitor the results closely each morning.

This is a high pressure. The doc has mentioned BIPAP and if FeelingBetter has problems tolerating the high pressures a BIPAP might be a good solution.

Unfortunately this doc seems to have a very poor understanding of how to take advantage of the functionality of APAPs.

FeelingBetter,

Here is something I found in someone's old post about posting images. It looks like it is still current.
From within Encore Pro (or Encore Viewer):

From the report view, click File, PDF Export.

Save your report as a pdf in a place on your hard drive that you can remember. Change the name so that it includes the date.

Next, double click on the pdf file you just exported.

This will open Adobe Reader. Now go to Tools, Select and Zoom, Snapshot tool. This will bring up a x shaped cursor.

Left click and move the cursor over the area you want to copy. Release the click and that area will be copied to your clipboard.

(If you use Foxit Reader it is just Tools, Snapshot, and follow the same procedure. )

Now open the Paint application that came with your computer. Click on the empty white page, and use Control-V or Paste to paste the clipboard image into Paint. Now Save As and select the jpg extension. Once again, save somewhere you can remember.

Go to Photobucket.com, and open an account. Log into your account, and Click Choose Files from the front page Upload Images and Video. If you want to upload multiple files, use the bulk uploader.

Once you have uploaded a jpg picture, when you hover your mouse over the image, you will see links below it. Select the IMG code link, highlight it, use Control-C to copy it to the clipboard.

Now make your post, and where you want the Encore Pro chart to go, use Control-V (paste) to paste in the IMG link. This will automatically link to the jpg on Photobucket, and will show up in your post.

Tips: Change the name in your copy of Encore Pro to your first name, or a pseudonym, or every page will show your full and real name.

You can also change the size of the picture on Photobucket if it doesn't show up right in your post.
